Application filed March 3,1926. Serial No. 91,978.

Irv present invention has to do with he provision of a peculiar and advanta- 'cous gauging device, susceptible of being 'eadily manipulated. and possessed ofv a ide range of usefulness as hereinafter set forth.

To the attainment of the foregoing the invention consists in the improvement as l'iei'einafter described and definitely claimed.

in the accompanying drawings forming part of this specification Figure l is a face view of the device constituting the best practical embodiment of my invention of which I am cognizant.

Figure 2 is an edge elevation of the device. I V

Figure 3 is a rear elevation of the device.

lligure is an enlarged detail horizontal section taken in the plane indicated by the line 55 of Figure 3. i

Similar numerals of reference designate corresponding parts in all of the viewsjof the drawings. Y 7

Among other elements my novel gauging device comprises a body 1 having finger holes 2 to facilitate manipulation thereof, and also having, by preference, an aperture 3 in which is disposed a spirit level i, the sait spirit level t being preferably, though not necessarily, comprised in my improvement. i V

In. the rear side of the bod 1,, I provide circular countcrsinks 5, and said countersinks are in connuunication with circular. apertures of reduced size which extend through to the face of the body 1, Figure 5. Snugly arranged in and revoluble in the counter-winks 5 are circular disks 7 With reduced journal portions '8 and also with reduced angular portions 9, Figures 1 and 5. from which extend screw shanks 10. As shown in Figure 3, the countersinks 5 are preferably grai'luated to 360 degrees. It will also be noted by reference to Figure 3 that zero points 11 are provided at the rear side of the base 1. p

in addition to thebody 1 my novel device .cou'iprises two long wings 12, and two short 13. Each of the wings 12 is provided with a tl-l and-a slot 15, the slot l l being for the reception of the before meni' 'auging tools or devices, and contemplates.

tioned angular portions 9 'complementary to the disks 7 so that swinging of the Wings 12 will be attended by turning of the.

disks 7.

Arranged aboutthe screw shanks l0 and against the faces of the wings 12 are Wash ers 16, and opposed to the said washers 16 are nuts 16* which are knurled and are recessed at 17 to receive coiled springs 18, the

said springs being designedto prevent falling of the wings12 to one side when the nuts 16* are loosened.

'ihc short wings l3'are' slotted at andare recessed at their rear sides as desig natcd by 23, and seated in the said recesses it; of the wings 13'ai'e angularbo'lt heads 27, the shanks of the bolts being designated by ZS and being extended through the slots 25 and 15 of the wings l3 and 1.2, respectively, and being also extended through washers 29 and nuts 30,'t he said nuts 30- being recessed as designated by 31 to receive coiled springs 32,,Ydesigned to prevent casual movement of the 3 parts When the i ilts 30 areloosened. f

The long Wings 12 are provided with graduated scales such illustrated in Figure 1, which scales are preferably similar to those of a six inch scale, and it Will-also be noted that pointers 40 are preferably provided on therevoluble disks 7.

It will be apparent from the' foregoing that my novel device is of siinple,"-i nexpen sive and compact construction, and yet is adapted to been'iployed as an angle gauge, a cinrvature gauge, a depth gauge, a com pass, a width gauge and asins'ide and outside calipe, -three pointcelipers bevel protractor, square. head, spirit level and trisquai e.

In using the device as a compass, a scratch awl. or scriber isheld at the end of one of the Wings and the thumb screw complementary to said wing is loosened so as to permit ofthe wing being swung so that the scratch aivl Or scriber will describe the arc of a circle.

My novel device turning the base up on the edge parallel to the level glass.

My device is also. adapted to be used as a depth gauge and when it is to be so used, the short wings are removed and the long Wings are adapted longitudinally to the depth required and the thumbscrevvs aretightened.

may be used as alevel by of a driving box with a View to obtaining the correct angles of the shoulders of the a box. In the said-use ot the gauge it is'placed are scribed on the ends ing of said embodiment.

in thedriving box and set to the size of the driving box shoulders. The gauge asset is removed from the driving b0); and placed on the end of the driving angles of the shoulders of the driving box oi the brass.

I have entered into a detailed description of the preferred cmhodin'icnt or my invention in order to in'ipart'an exactunderstandhowever, to be understood aslimiting' myself to the specific construction and arrangement of parts as disclosed, myinvention being detined by my appended claims within the scope of which modifications in structure and in arrangement may be made without departure from my invention. 7 I 'Havmg described. my invention, what I claim and desire to secure by Letters-Patent,

1. 111a gauging device and incombination, a bOC yhaving countersinks in one side and journal apertures in oon'nnunication with said countersinlts, slotted wings arranged at the other side of the body, slottedwings designed to extend at angles to the first-named slotted wings, the secondnamed slotted: wings being recessed at their rear sides, 'evoluble' disks disposed in the C(JlllltGI'SiHliS 'ol the body and having journal portions arranged in "the. journal apertures of the body'and also having angular portions disposed in the slots of thetirst-named wings and threaded shanks extending from said angular portions, recess'ed nuts mounted on said shanks, washers mounted on said shanks and interposed between the firstnamed wings and the nuts, coiled springs housed in the nuts and interposed between box brass, and the I do not desire,

the nuts and the washers, bolts having angular heads disposed in the recesses of the tirstnamed wings, Washers mounted on said shanks anc arranged against the faces of the first-named wings, nuts mounted on. the

s .anks and, PIOv'lClECl with recesses, and springs housed in. the nuts and interposed bet veen the washers and the nuts.

2. In a gauging device and in combination a body having 'countersinks in one side and journal apertures in communication with said count rsinks, slotted wings arranged attlie other side of the body, slotted wings designed to extend at angles to the lirst-named slotted wings being recessed at theinrear sides, re'voluble disks disposed in the *coim tersi ks of the body and having journal portions arranged in the journal apertures of the body and also having angularportions fpOSOtl in the slots of the first-nai ed wings and, threaded shanks extending from said angular portions, recessed nuts mounted on said shanks, washers mounted on said shanks and interposed between the first-named wings and the nuts, coiled springs housed in the nuts and interposed between the nuts and the washers, bolts having angular heads disposed in the recesses of the second-named wings and also having threaded shanks extending through the slots of said wings and also throu 'h the "slots of the tirstnai'ned wings, washers mounted on said shanks and arranged against the faces oit the first-named wings, nuts mounted on the shanks and provided with recesses, and springs housed .in

slottedwings, the second-named the nuts and interposed between the washers and the nuts; the first named wings being provided with scales, and the countersinks in the back of the body being graduated to degrees.
